Adam opened his eyes after spending 3 days in the Physical Dungeon and 3 days in the Soul Dungeon, which altogether was 3 days in reality.
In those 3 days, his Physical and Soul Cultivation were both progressed to the Master Cultivation Level but it was at the cost of greatly damaging his Physical and Soul Dungeon Forms to the point of near-death.
They were both tough battles that required him to have great power, but also great skill and he had used most of his abilities that he had access to, but Adam still felt that he could draw out even more power than that.
The battles were great tests for his power and granted him great rewards, but had repercussions.
It greatly affected his soul and body to the point that he wouldn't be able to return to the dungeon for quite a while, but Adam was fine with that as he needed to adjust to his great power and there were still many things he needed to do.
